13 Right not to suffer unauthorised deductions.E+W+S
(1)An employer shall not make a deduction from wages of a worker employed by him unless—
(a)the deduction is required or authorised to be made by virtue of a statutory provision or a relevant provision of the worker’s contract, or
(b)the worker has previously signified in writing his agreement or consent to the making of the deduction.
(2)In this section “relevant provision”, in relation to a worker’s contract, means a provision of the contract comprised—
(a)in one or more written terms of the contract of which the employer has given the worker a copy on an occasion prior to the employer making the deduction in question, or
(b)in one or more terms of the contract (whether express or implied and, if express, whether oral or in writing) the existence and effect, or combined effect, of which in relation to the worker the employer has notified to the worker in writing on such an occasion.
(3)Where the total amount of wages paid on any occasion by an employer to a worker employed by him is less than the total amount of the wages properly payable by him to the worker on that occasion (after deductions), the amount of the deficiency shall be treated for the purposes of this Part as a deduction made by the employer from the worker’s wages on that occasion.
(4)Subsection (3) does not apply in so far as the deficiency is attributable to an error of any description on the part of the employer affecting the computation by him of the gross amount of the wages properly payable by him to the worker on that occasion.
(5)For the purposes of this section a relevant provision of a worker’s contract having effect by virtue of a variation of the contract does not operate to authorise the making of a deduction on account of any conduct of the worker, or any other event occurring, before the variation took effect.
(6)For the purposes of this section an agreement or consent signified by a worker does not operate to authorise the making of a deduction on account of any conduct of the worker, or any other event occurring, before the agreement or consent was signified.
(7)This section does not affect any other statutory provision by virtue of which a sum payable to a worker by his employer but not constituting “wages” within the meaning of this Part is not to be subject to a deduction at the instance of the employer.
